        super(Example, self).__init__(*args, **kwargs) 
        self.InitUI() 
  
    def InitUI(self): 
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH) 
        self.toolbar = self.CreateToolBar() 
        td = self.toolbar.AddTool(1, '', wx.Bitmap('sep.png')) 
        te = self.toolbar.AddTool(2, '', wx.Bitmap('wrong.png')) 
        tf = self.toolbar.AddTool(3, '', wx.Bitmap('right.png')) 
  
        self.toolbar.Realize() 
        self.Bind(wx.EVT_TOOL, self.OnOne, td) 
  
        self.SetSize((350, 250)) 
        self.SetTitle('Undo redo') 
        self.Centre() 
  
    def OnOne(self, e): 
        # insert stretchable space b / w separate  
        # and tick tool at position 1 
        self.toolbar.InsertStretchableSpace(pos = 1) 
        self.toolbar.Realize() 
  
    def OnQuit(self, e): 
        self.Close() 
  
  
def main(): 
  
    app = wx.App() 
    ex = Example(None)

    def OnOne(self, e): 
        # insert stretchable space b / w tick and cross tool at position 2 
        self.toolbar.InsertStretchableSpace(pos = 2) 
        self.toolbar.Realize() 
  
    def OnQuit(self, e): 
        self.Close()
